Inventor: TOYOFUKU SHINICHI
IPC: E02D5/08
Filed: 1994-11-17
Abstract: PURPOSE: To prevent underground water from flowing in, by fixing a partitioned part of the inside of a main body along the longitudinal clearance formed in the cylindrical main body, to the longitudinal fixing part provided at the outside of the main body and filling the partitioned part with a sealing material. CONSTITUTION: A pipe 10 containing a sealing material 28 in the space 20 of a partitioned part 16 is arranged at the rear end of a shielding tunnel excavator having a nearly same section with the main body 12. The pipe 10 is advanced to an aimed shaft together with the excavator by a pusher in a starting shaft and then the fixing part 18 is fixed to the partitioned part 16 to lay a new pipe 10 adjacently to the pipe 10. The fixing part 18 is caught by the seal material 28. Further, on laying it, a powdered or a slurry solidifying water- sealing material is charged from a connected part 24 to cut off fine clearances. Underground water and mud slurry for excavation, etc., are prevented from flowing into the starting shaft through the space 20 during installation of pipes or after installation of pipes.  In this way, an excavating machine making use of mud slurry can be used and the pressure decrease at the working face side can be prevented.
